GEMCAL D3 TABLET includes calcium carbonate and vitamin D3 (cholecalciferol), both of which are categorised as calcium supplements and vitamin derivatives, respectively. Calcium deficiency is treated with it as well as prevented (low levels of calcium in blood). Low levels of calcium are linked to inadequate dietary calcium intake, which is primarily found during pregnancy and lactation. Additionally, GEMCAL D3 TABLET is used to treat rickets (abnormal calcification, softening and deformation of the bones that generally results in bowlegs) and hypoparathyroidism. Osteoporosis causes bones to become brittle and fragile (low levels of parathyroid hormones).Disclaimer:For more information contact your physician.
